Against the backdrop of significant differences in agricultural scenes between the north and south of China, traditional rotary tillers often face challenges such as being "usable in dry fields but difficult to operate in paddy fields" or "adaptable to paddy fields but inefficient in dry fields", resulting in cost pressures for repeated equipment purchases and inconvenience in job switching for farmers. The dual-purpose rotary tiller for water and drought, with its innovative design of "one machine adapted to dual scenarios", breaks through the limitations of scenarios and achieves rapid operation of paddy field plowing and dry land soil crushing, becoming a "versatile" tool for improving agricultural efficiency.
Its core advantage stems from targeted structural optimization. In response to the muddy and prone to sinking characteristics of paddy fields, the dual-purpose rotary tiller for water and drought uses widened anti-skid tires or a tracked walking system to increase the contact area and reduce the contact pressure. Even in deep muddy paddy fields, it can travel smoothly and avoid wheel sinking; At the same time, the machine is equipped with a rotary tillage blade set designed to prevent entanglement with grass. The blade body is made of wear-resistant alloy material, and the cutting edge has undergone special heat treatment. It can not only chop rice stubble and weeds in paddy fields, but also prevent straw from entangling the blade shaft, ensuring smooth operation. Facing the hard soil layer of arid land, the equipment can quickly break the compacted soil and create a loose and uniform planting bed by adjusting the rotary tillage depth (up to 30 centimeters) and blade speed, meeting the sowing needs of dryland crops such as corn and wheat.
In terms of work efficiency and cost control, the dual-purpose rotary tiller has significant advantages. In traditional farming, farmers need to purchase paddy field rotary tillers and dry land rotary tillers separately, which increases equipment investment costs by more than 30% and occupies a large storage space; The dual-purpose model for both water and drought does not require additional modifications. It only needs to adjust the cutting tools or walking parts according to the scene to achieve "one machine switching". A single device can complete two scene operations, and the equipment purchase cost is directly reduced by nearly half. In addition, its operational efficiency can reach 1-1.5 acres per hour, which is 20% -30% higher than traditional single machine models. Taking the cultivation of double cropping rice in the south as an example, farmers can complete the plowing of 10 acres of paddy fields and the soil crushing of 10 acres of dry land within 3 days using this equipment, saving nearly 2 days of time compared to traditional equipment and significantly reducing agricultural time.
From pre seedling preparation in paddy fields in southern rice growing areas to pre sowing land preparation in northern dryland areas, the dual-purpose rotary tiller is suitable for various agricultural needs. It not only solves the limitations of traditional equipment scenarios, but also reduces the burden on farmers and improves work efficiency through "one machine for multiple uses", becoming an important equipment for promoting large-scale and intensive agricultural production, helping farmers easily cope with different farming scenarios, and achieving "one season farming, one machine for all".
